Meta tag
Audio: trumpetpodcast16.m4a
Republished all - to make sure audio file got loaded again - (not overwriting CMS -doing all online)
Checked on line CMS - path is correct - name is correct
Sometimes will play - sometimes will not
Very Strange
For some reason - I checked all the other podcast files - no brackets…
Must be that - How did it get added?
@ben seems to be adding brackets on the meta data in CMS V2
Thanx will change that - didn’t know about that…
quick update here to say we’ve fixed the underlying cause of those mystery square brackets 
The Online Editor’s frontmatter serialiser could turn a field into an array under certain conditions (emptying a field and refilling it was the usual trigger), and one corrupted file could then flip the detected field type for the whole folder — which is why a single podcast post had brackets when the rest didn’t.
From the next Elements 3 update, fields always save as plain strings, and re-saving an affected post in the editor cleans up any brackets already there. No more downloading the CMS folder to hunt for them
